Another crash after re-attempting partitioning

Description zohn.joidberg 2015-09-04 21:13:14 UTC 
Application: baloo_file (5.6.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-26-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:

I created a new FAT32 partition on a USB stick using gnome-disk-utility 3.14.0 (UDisks 2.1.5 (built against 2.1.4)).
Baloo suddenly crashed, presumably after the partition was created trying to index it. The plasma desktop disappeared for a while and then came back.

- Custom settings of the application:
Baloo still had the default settings, i.e. no directories to skip listed.

-- Backtrace:
Application: Baloo File (baloo_file), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

backtrace of plasma crash which happened at the same time

Apparently plasma crashed at the same time as Baloo. I'm attaching the corresponding backtrace.

Another crash after re-attempting partitioning

Another Plasma crash after re-attempting partitioning.
Baloo search was disabled beforehand this time.
Comment 3 zohn.joidberg 2015-09-14 22:42:32 UTC 
"Workaround" for the partitioning:
I've had several more plasma crashes since last time, whether using the KDE partition manager or the gnome-disks.
gnome-disks tended to always crash while trying to create the second ext4 encrypted partition on the flash drive, after having created a first FAT32 partition.
The error message seemed to always be:
"Error wiping newly created partition /dev/sdb2: Command-line `wipefs
-a "/dev/sdb2"' exited with non-zero exit status 1: wipefs: error:
/dev/sdb2: probing initialization failed: No such file or directory
 (udisks-error-quark, 0)"
As a workaround, I installed openbox to run gnome-disks from there, but the crash still happened.
Based on this https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=767457 , I ran the failed wipefs command manually and then successfully created the encrypted partition from within gnome-disks.

Anyway, while it seems baloo/plasma were not behind the partitioning failure, they still seem to have crashed because of it.
[although despite running openbox, some KDE stuff was running:

Some dmesg output. It seems there was a kdesu segfault.
